Yes appologies I'm using the Ch340G drivers. How do I do a loopback test? with the arduino or CH34?..
I get a flashing blue LED on the CH34 when I try and upload the code.
GND - GND
VCC - VCC
TX - RX
RX - TX
DTR - unmarked DTR on arduino (next to TX)
Only a power LED on the Arduino, no flashy no nothing..
